On the wedsite, it notes: the preliminary ShapeNetCore v2 was incomplete and had different normalization than ShapeNetCore v1. Could you tell me more details about the normalization method? And what is the diagonal normalization in shapenetcore v1?
For shapenet v2,
v_norm = (v-centroid) / norm(diag),
where:
The normalization scripts are here:
